Hello, Great info. CAn’t seem to find my fuse though. I have a 2014 Prius V 5 and can’t locate the fuse for the rear door latch. Any ideas?
Thanks
Mike
In the case of accidental reverse polarity which fuse would that blow? I think it’s the 125 fuse/relay? Do you know? I see it at bottom of diagram. But I can’t see where it is in actual fuse box? Is it the big long white fuse/relay? Plz advise. Thank you
